Red-Eared Sliders Update

Well, a few months ago i posted my RES turtles and i've decided to do a little update. Last time i posted they were small and swimmin around in a 10 gallon tank. Now, they've grown quite a bit and i've got them swimmin in a nice 50 gallon tank. I took one of my old 10 gallon tanks and flipped it upside down and cut out 2 of the sides. I placed some slate on the upside down tank and then placed it in my 50 gallon so they have a nice basking area. I also decorated the tank with some rocks and a nice piece of drift wood for them to climb onto their basking area. All i need now is a new filter, even though my old filter seems to work better in this tank then it did in my other which is weird. It's still something i gotta do though, so hopefully in the near future. I'd also like to get them another UVB light. Well, hope you guys dig the new setup...
